Hey Guys,

So I'm just about done with the LED taillight project.

To bring everyone up to speed. I bought the Hella F150 LED taillights and only the lower 3 celis bars operated as the running lights and the upper LED array did the brake/turn lights.

Well I started to work on them myself to rewire and make the taillights work so the upper LED array and the lower 3 celis bars operated together as brake/turn/parking.

Needless to say it was a VERY difficult task and ended up enlisting the help of a friend on another forum who is very good with LEDs. He was able to find a solution and help me out. However, without his approval I cannot release how it's possible. It doesn't really matter anyhow because it is extremely difficult to figure out and do, and I guarantee 99.9% of you who read this will not want to do it. So don't worry or complain.



One of the things I still need to do is install a "no-load" flasher. Since the LED taillights will pull less electricity the truck will think I have blown turn bulbs and will start the "hyper-blink" stuff. I don't want to install load resisitors that will make the truck think there are halogens in the back which take the correct amount of electricity because the run very hot and are dangerous to have wired into you truck due to heat reasons.

Well I bought a "no-load" flasher at my local automotive store.

Here is what I need to know. Where is our flasher located so I know where to start looking to try out the "no-load" flasher before I re-install the taillights?

Thanks,

Duke

 

Only place I could think of is in or around the fuse box... I dont remember seeing anything but then again I was never looking for it.

Post up some pictures when done..

 

Will do. I'm actually pretty sure it's in near the steering column as that is where the ticking comes from when you have your turn signal on. I just want to see if you can get to it without having to take the speedo area off.

Trying to cut down on my "hunting for it" time.

Duke, are you using a PWM and hooking it to all of the LEDs?

 

It includes a PWM but it's much more then that as it requires taking the entire taillight apart and rewiring the circuit boards.

Anyone know where the flasher is?

Duke

 

duke i can get you info on where the flasher is located if you give me a few minutes

 

let me know if i can help you find another diagram

and that diagram is specifically for 2005, but may also be used for other years, but i can only verify its accuracy specifically for 05

 

Thanks! I'm not in a huge hurry. I won't be trying this no load flasher I got a Checker auto parts until tomorrow.

I want to test it and make sure it works/fits/isn't too loud. It says "loud no load flasher" but I don't know if that means it's the same loudness as stock or louder. If it's louder then I'll look at other auto parts stores for a quieter no load flasher.

you must type slow, since i replied 2 minutes before you posted this

 

Awesome diagram! It looks like I won't need to pull the upper dash panel after all since it looks to be in the bottom under the dash on the driver's side corner.

I'll give it a try tomorrow and we'll see what happens. Something tells me the no load flasher will be way too loud and I'll need to look for a quieter one.

Thanks again for the diagram!

Duke

 

LOL, I was working on something else and left the reply box open with out pushing "Submit Reply".

Duke

 

sure....

is that diagram what you were looking for?

 

I believe it is. I can't think of another flasher relay that is up under the dash.

I'll know more tomorrow. I'd look once I get to the truck but I don't want to crawl up under there with road salt on the floor matts in my dress clothes.

If you did want to go the resistor route I can say from experience that they arent that big of a deal. I used two for my front blinkers and they work fine.

 

Yeah I know they're not a "big deal" or hard to wire or anything of that nature. But I've tested them and they get VERY hot and I don't want to run the risk of them touching the back of the taillight or anything else and burning or melting.

I'm going to give the no load flasher option a try first and we'll see how it goes.
